                     IF … ELSE … STATEMENT

                     The if…else… statement lets your program choose between two options. Python checks the
                     condition; if it’s true, it executes statement block 1 after the if statement—otherwise, it executes
                     statement block 2 after the else statement.                    Start
                     Syntax of the if … else … statement:

                     if (condition):
                                                                                  Input Age
                         Statement block 1
                     else:
                                                                                                     False
                         Statement block 2                                        Is Age>18?
                     Note  that  both  statement  blocks  1 and 2 are
                     indented. Block 1 is under if, so it will be executed              True           Print ‘Not Eligible’
                     if the condition mentioned is True. Block 2 is under        Print ‘Eligible’

                     else, so it will be executed if the condition is False.
                     Here, if the age of the user is more than 18, ‘Eligible’
                     will be printed, otherwise ‘Not Eligible’ will be printed.      Stop

                      Program 3 To show a message if the user is ‘Eligible’ or ‘Not Eligible’ to cast a vote.

                         Program3.py
                      File  Edit  Format   Run    Options   Window    Help

                      age=int(input("Enter Age: "))
                      if ( age>=18):
                          print("You are eligible to cast a vote.")
                      else:
                          print("You are not eligible to cast a vote.")

                         Output

                      Enter Age: 25
                      You are eligible to cast a vote.

                      Enter Age: 15
                      You are not eligible to cast a vote.
